Look at the 2 consecutive credits:
Julia Nickson
Lei Shun

Then look at the top right of the poster.
Ju Li Ah.Nei Ke Shun

Lei Shun looks like an incorrect and abbreviated version of Julia's surname.

The only other credit for this Julia is
Whores Of The North. HKFA credits Ma Li A, so this second credit looks doubtful.

If nobody stops me in 7 days I will remove Lei Shun.

Margaret Lee's role is a (taoist) magician and not a witch.
If nobody objects in 10 days, I'll change her role.
